INSPECTION OF EFI MAIN RELAY
1. INSPECT RELAY CONTINUITY
(a) Using an ohmmeter, check that there is continuity between
terminals 1 and 3.
(b) Check that there is no continuity between terminals 2
and 4.
If continuity is not as specified, replace the relay.
2. INSPECT RELAY OPERATION
(a) Apply battery voltage across terminals 1 and 3.
(b) Using an ohmmeter, check that there is continuity between
terminals 2 and 4.
If operation is not as specified, replace the relay.

INSPECTION OF CIRCUIT OPENING
RELAY
1. INSPECT RELAY CONTINUITY
(a) Using an ohmmeter, check that there is continuity
between terminals STA and E1.
(b) Check that there is continuity between terminals B
and FC.
(c) Check that there is no continuity between terminals B
and FP.
If continuity is not as specified, replace the relay.
2. INSPECT RELAY OPERATION

2. INSPECT VOLTAGE OF ECU
Check the voltage between each terminal of the wiring con-
nectors.
wTurn the ignition switch ON.
wMeasure the voltage at each terminal.
HINT:
wPerform all voltage measurements with the connectors
connected.
wVerify that the battery voltage is 11 V or more when the
ignition switch is ON.
Electronic Controlled Unit (ECU)
INSPECTION OF ECU
HINT: The EFI circuit can be checked by measuring the
resistance and voltage at the wiring connectors of the ECU.

COMPRESSION CHECK
HINT: If there is lack of power, excessive oil consumption or
poor fuel economy, measure the compression pressure.
1. WARM UP AND STOP ENGINE
Allow the engine to warm up to normal operating tempera-
ture.
2. DISCONNECT COLD START INJECTOR CONNECTOR
3. DISCONNECT DISTRIBUTOR CONNECTOR
4. REMOVE SPARK PLUGS (See page IG±6 or 11)
5. CHECK CYLINDER COMPRESSION PRESSURE
(a) Insert a compression gauge into the spark plug hole.
(b) Fully open the throttle.
(c) While cranking the engine, measure the compression pres-
sure.
HINT: Always use a fully charged battery to obtain engine
speed of 250 rpm or more.
(d) Repeat steps (a) through (c) for each cylinder.
NOTICE: This measurement must be in as short a time
as possible.
Compression pressure:
12.5 kg±cm
2 (178 psi, 1,226 kPa) or more
Minimum pressure:
10.0 kg/cm
2 (142 psi, 981 kPa)
Difference between each cylinder:
1.0 kg/cm
2 (14 psi, 98 kPa) or less
(e) if the cylinder compression in one or more cylinders is low,
pour a small amount of engine oil into the cylinder through
the spark plug hole and repeat steps (a) through (e) for cyl-
inders with low compression.
wIf adding oil helps the compression chances are that the pis-
ton rings and/or cylinder bore are worn or damaged.
wIf pressure stays low, a valve may be sticking or seating is im-
proper, or there may be leakage past the gasket.
